Trick Photoshop

Sometimes an image may look all right, but needs a boost to make it it better. The easiest way is to used a Color Balance and Curves Adjustment layers. It is not difficult to do. To this a little bit of Light Shaping will add to the overall improvement of the image.

Step 1 : I have opened this free stock image. It looks OK, but could look better. You will find the image here

It belongs to mechtaniya
The improved image.

Step 2 : Click the New Fill or Adjustment Layer button at the bottom of the Layers palette. Click Color Balance from the pop up.

Step 3 : The Color Balance Adjustment dialogue box opens.

Step 4 : I have first clicked on Shadows. The adjustment will only affect the shadows or dark portions of the image. Remember every image is different. Therefore the settings will vary. You need to examine first what needs to be boosted in the shadows, whether it is red or Cyan, Magenta or Green or Yellow or Blue. It is not necessary that all the three adjustments are required

In this image I have increased the Red to +9 to bring up the reds, likewise Green which I have given a value of 3 to boost the greenery in the background. I  have given an adjustment of -6 to the Blue (which increases the yellow in the image). There are two colors on the end of each scale you will notice. For example if you increase the Red, the Cyan is decreased. Therefore study the image and see where the color boost is to be applied, whether it be the Shadows, Midtones or Highlights. In the Shadows only the shadows are affected.

Step 5 : Click on the Midtones. The adjustments that you make will only affect the midtones and not the Shadows or Highlights.

Step 6 : You will notice that the image has a yellowish cast. In the Midtones I have given +1 for Red to counter the yellow, -8 for Green as there is no green in the image, which boosts the Magenta. Lastly I have given +5 for the Blue to decrease the yellow.

Step 7 : I have now clicked on the highlights. This will affect the skin tone largely. I have given +3 to Red, -12 for Green and +12 for Blue.

This is how the image looks. Now to give a Curves Adjustment.

Step 8 : Click on the New Fill or Adjustment layer button. Click on Curves from the popup.

Step 9 : The Curves dialogue box opens.

The Layers palette meanwhile looks like this.

Step 10 : In the Curves, click on the diagonal at the top approximately in the middle of the top right square. what you re doing is increasing the light.

Step 11 : Drag up slightly at the bottom. It decreases the shadows. The face of the girl has some shadows which need to be lightened.

The image looks like this.

.Step 12 : Make a second Curves Adjustment layer.

Step 13 : At the top drag the diagonal slightly upwards, at the bottom drag slightly inwards. Place the cursor in the middle of the diagonal and use the Up Arrow key to nudge it slightly up.
